Tangential-radial traction suturing technique for intrascleral foreign material implantation

We used an intrascleral implantation technique to anchor a keratoprosthesis in the limbal sclera of 22 rabbits' eyes. The tangential-radial traction used in this procedure enabled multivectorial traction forces to be applied while maintaining a tight junction between the biological tissue and the foreign material. During 29 weeks of follow-up there was no postoperative leakage, no cataracts developed, and the anterior chamber was maintained in all the eyes at all times. No ocular infection developed in any eye during the first postoperative month. The compound-force traction used in this procedure may prove useful in other areas of ocular surgery.
